Bundles of cash have mysteriously been appearing across Japan from an anonymous donor. Accompanying the wad of cash was a handwritten letter requesting that the money be used for training and education. Over the course of the week, similar discoveries were made in 20 locations across Saitama and Akita prefectures, amounting to a total of ¥200,000 (roughly $1600). This strange and mysterious case has been one of the biggest news stories out of Japan in recent weeks. Since the locations of these incidents varies throughout Japan and not concentrated in a single region, it’s hard for officials to pinpoint the source of the cash.
